    Department of Defence = dod
    IAP – Instrument Approach procedure

    For most civil airports in the US, the FAA Aeronautical Information Services develops instrument approach procedures according to the US Standard for Terminal Instrument Procedures (TERPS). The Department of Defense (DOD) also has a standard for the design of instrument procedures that it uses for military airports. Many of those procedures are based on TACAN navigation systems and equipment that the civil aviation fleet is not equipped with. Many of these charts are included in the FAA publication as well as in the DOD FLIP.
